Pfft, that 75 day level wasn't that difficult. You can always make it easier if you play the game at half speed. As with all RTS, single player difficulty = game speed.

Build 2 of each of the critical guilds: 2 warrior guilds, 2 ranger guilds, 2 healer guilds. Establish both northern trade routes after killing all of the level 1 spawns in the north. You'll be rolling in money. Form up parties. The bear-ish creatures will take down your buildings quickly, put cheap attack flags on them before they get close.

The demo is amazingly fun. I'm quite happy I had already pre-ordered a while ago.

If you actually read the PDF, you would know it discusses the user communities self organization and the online improvement resources that the users have created. It doesn't isn't talking about WoW itself.

I briefly played with a beta a few months ago too. Hope things have improved. The client performed very poorly on my PC. The tutorial stuff had OK performance but once I got above ground, it became an ugly, unplayable, stuttering mess.
